04 is the best years...ive owned 3 04's...03's have their lil issues as for lsd and having to go stage 1 and the tuning issues with stage1's...and 05's have their lil sensor issues and and lil problems i always say 04's are the best as for they dont have the sensor issues.,..and stage 0's are the best.....if u got a 03 and put lsd it will be fine..but as old issues with my friends cars with tuning 03 with stage 1 computers they add fuel all the time on top end but u can get around it also...but i own a 04 now and dont have any problems i love it...and im also one of the only 11 sec stock turbo srts in central fl
